Abstract
In today's world, the surrounding environment of IT service activities is rapidly changing. Naturally, the roles of IT service managers, who are responsible for the operation services of their client systems, are expanding. The service managers should face the reality and fulfill their roles to achieve their service business targets. I have put together a concrete approach for that, based on five different viewpoints. I would like to take this opportunity to present the essential points of the approach, while also briefing how the service managers should conduct the activities.
